To attack-0m it may concern:

Be 1t known that I, ANDREW J. Burns,

a citizen of the United States, residing at.

Sandusky, the county'of Erie and State of Ohio, have invented certain new and useful Improvement invApparatus for Blowing Glass; and I 1.0 hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had,

to the accompanying drawings, andto the, letters and figures of reference marked there-' on, which form a part of this specification.

This invention relates to new and useful improvements in apparatus for drawing glass articles, either hollow cylinders or other shapes, from a bath of molten glass, and comrises various details of construction, cominationsand arrangements of parts which will be hereinafter fully described and then specifically defined in the appended claims. My, invention is illustrated in the accompanying drawings, in which:'

. Figure 1 is a front elevation of the apparatus, portions being shown in vertical section. Fig. 2 is a similar view showing the apparatus in a'raised position, showing the manner in which the parts would be positioned when the cylinder is completed. Fig. is an edge view showing the parts in the positions-illustrated in Fig. I. Fig. 4 is an enlarged detail viewof a valve apparatus for controlling the supply of air to theblowers. Fig. 5 is an en: larged'detail view showing means for closing theair-sup ly pipe when a blow pipe is removed, an Fig. 6 is a detailed view of the valve mechanism shown in Fig. 5 closed as the blow ipe is removed.

Re erenee now being had to the details of the drawings by letter, A and A designate two pots or receptacles for holding molten glass, having the removable bottoms A? so arranged that any glass remaining upon the upper surface thereof may be melted. as thev bottom is lowered in the manner shown in pot designated by letter A. Rising between said pots or receptaclesis a standari'l --B upon which a vertically movable cross headO is mounted, which latter isproviecd with grooved wheels C journaled in portions I of the cross head which extend laterally be 'OI1(l saidstandard B and adapted to bear frictionally' against theouter edges thereof.

Mounted upon the arms C of the cross. head are the blow pipes C and C designates an the valve is adapt'e with the opening in the the-blow pipe is removed lrom the tubing dju stable collar which is movably held upon the blow pipe and rests upon one of the crosspieces C rovidin-g means whereby the blow.

designates an air pipe which is horizontally disposed and connected at each end 'with a valve casing D, each of which has a spring-pressed valve D therein having a tubular extension (1, enlarged'detailso'l' which are shown in Figs. 5 and 6. Said valve casing has a shouldered ortion D a ainst which to. seat. aid tubular extensiond has an opening d in the circumference thereof. The lower end of the tube (1 is adapted to be en a ed by the upper end of the blow pipe to 10 d said valve in the position shown in Fig. 5 when it is desired .to allow air to pass through the blow pipe, in. which position the opening (1 w ill register pipe D. When (1, the latter will assume the position shown in Fig. 6, the supply of 'air'bemg automaticl JE designate series of sections of ipe pivoted together at F, and the enter on s of theseetions E are also provided with airtight connections, the joints being so arranged as to allow the sections to fold in the manner showniin Fig. 2 of the drawings in the form of lazy tongs. The lower ends of the sections E are connected to the pipes E which are. pivetally connected to a union D which communicates with the pipe D. An air tank H is provided which has a ipe ll leading therefrom and through whic '1 air is ,J which in turn are ivotally connected to and communicate wit 1 the uppermost of the pipes-E, as shown clearly in Fig. 1 ol' the drawmgs. In order to maintain a uniform pres- Mounted within said N The incoming air entermg the valve sure of air in the cylinder ll during the draw- I ing process, an exit K for the surplus air leads from the 'upper portion oi the valve casing l and the air, in order to pass through said exit raised and lowered, to assume the different positions shown in Figs. 1 and 2 of the drawlugs, to actuate the plungers in said valve Q the to regu said pipes.

Mounted in suitable bearings upon the cross-piece R of the-standard 1s a shaft R pipe K, passes through the slot L in the plunger I and thence into the upper ortion of the casing from which it asses to t e pipe K. In order to pro erly a just said plunger, I rovide the rods and N, the former of w ich are fastened at their upper ends to a crossiece N through which the threaded end 0 the plunger stem N, which is fastened to the plunger I, passes, as shown clearly in Figs. 3and 4 of the drawings. Said crosspiece N has a strap N surrounding an adusting nut N which is mounted upon the threaded stem N The rods N are pivotally connected at N to the yoke N which latter is pivotally mounted upon the pins N Said rods N are pivotally connected at. their u per ends to the yoke N 7 and their lower en s are pivotally connected to a cross-piece N which is similar in construction to the-crossiece N 2 above described. Said cross-piece l is provided with a strap N having regis tering apertures therein for the reception of the threaded stem N which is fastened to the plun er I. Said yoke l is pivotally connects to a bar Q which in turn is pivotally connected at Q to one end of the lever 1pivot connecting said bar with the aving an elongated slot Q to allow for the adjustment of the bar Q. The lever Q is connected to one of the pipes J and is adapted, as the various pipe sections are casing to regulate the supplyv of air, thus making the actions of the p ungers automatic in the operation of the apparatus. In order ate the supply of air through the pipes K and H, suitable valves may be positioned at any locations for convenience of the operator and to assist in increasing or decreasing the supply of air passing through having moved reelsR? fixed thereto and to which the fiat straps R preferably of metal, are adapted to wind as the shaft R is rotated in any suitable manner, such as by the intermeshing gear wheels S driven from any suitable source of power. The lower ends of the straps R are connected to the cross head throu h the medium of the turn buckles S. T (Tesignates a crane which is pivotally mounted upon said standard and has 'a lever T pivotally connected at T upon the crane, said lever T having a hook T at one end for engagement-with the cover '1 for the molten glass potsv or receptacles, said crane being adapted to swing so as to bring the cover either over one pot or the other accordingly as may be desired. 1

The operation of my apparatus will be readily understood and is as follows :W'hen air-supply it is desired to draw a cylinder from one pot is imparted to the shaft R which will cause,

the cross head to rise and with it the blow pipes. The air is automatically fed through the pipes described leading to the blow pipes and, as the size of the reels increase in diameter ncident to thereeling up oi the stra s R3, the upward motion of the cross head and the blow pipes is accelerated. After the cylinder has been blown, a reverse movement imparted to the shaft it". will allow the cross head to move downward upon the standard, after which the blow pipe upon the other side of the apparatus may be utilized for drawing another cylinder from the other pot of molten glass. While one pot is not in use, the bottom thereof may be lowered as shown in Fig. 1 of the drawings and the cover placed over the pot in order to allow any glass which might remain upon said bottom to be meltedand run over the inclined top of said bottom of the receptacle. r

B y the foregoing, it will be noted that the two ots may be alternately utilized for blowing the. cylinders, one being prepared for the molten glass while the other is in operation for the blowing process.
